Electricity in a Vacuum: Investigating 1e9 Voltage

In summary, the conversation discussed the potential effects of applying electrical voltage in an ultrahigh vacuum and its potential to break the vacuum. It was noted that while vacuum breakdown is often referred to as a dielectric breakdown, it actually involves the presence of residual gasses. Further information and discussion on this topic can be found in the provided links.

Good day.

What happens if a vacuum to put two electrodes, 1 cm apart, and electrical voltage in 1e9?

Thank you.

Then your electric field strength is 1e9/1e-2 = 1e11 V/m. You probably cannot sustain this field strength without heroic efforts.

I have done a lot of work about 1e7 V/m ... if increased much beyond that my electron source arcs. This is not much better than dry air, even though it is in an ultrahigh vacuum (10^-9 torr).

This paper discusses many of the issues (1978):

But perhaps you mean "will it break the vacuum"? Such as this laser system may one day attempt:

All right.

But it may happen that the vacuum breaks.
And the gap will be trips charged particles?

Say again, please?

What you wrote here makes no sense. It is difficult to figure what you are asking:

English may not be your first language. However, this means that you need to write down a bit more explanation for the rest of us to understand what you are saying. So far, in your first three posts here, you have written quite a bit LESS than the one single post UltrafastPED made in Msg. #2.

One can break through vacuum, and what conditions must be fulfilled in doing?

What?

Please note that while it is often referred to as "vacuum breakdown", we are not really causing something similar to a dielectric breakdown in vacuum. From what we know now, the mechanism still requires the presence of residual gasses in the "vacuum".

1. What is electricity in a vacuum?

Electricity in a vacuum refers to the flow of electric current in a vacuum or near-vacuum environment. This phenomenon was first observed by scientist Michael Faraday in the early 19th century.

2. How is the voltage measured in this experiment?

The voltage in this experiment is measured using a high-voltage probe or a voltmeter. These instruments are designed to measure high voltages and can accurately measure the 1e9 voltage being investigated.

3. What is the significance of investigating 1e9 voltage?

Investigating 1e9 voltage, or one billion volts, is important for understanding the behavior of electricity in extreme conditions. It also has practical applications in fields such as high-energy physics and vacuum technology.

4. How is the vacuum created in this experiment?

The vacuum in this experiment is created using a vacuum pump, which removes air and other gases from the experimental chamber. This creates a low-pressure environment, allowing for the observation of electricity in a vacuum.

5. What are the potential dangers of working with high voltages in a vacuum?

Working with high voltages in a vacuum can be dangerous and should only be done by trained professionals. The main risks include electric shock, high temperatures, and the production of ozone. Protective measures and equipment should always be used when conducting experiments with high voltages.
